Motion 5 Troubleshooting!

Hi Guys!

I'm working on a project with Motion 5. I want a Logo (which I inserted into the program as a template) to be projected on the background behind. Therefore I put some lights in front of the template so that the light can shine through.
It should look like a stage-effect, where a logo is projected on the red curtain (which is my background).
Finally I added some more cool effects like particles that fly around in the light, to look more realistic,... that worked pretty well ( in Motion 5 itself)
but when I'm exporting the movie file,.. it just shows a black background and the particles flying around,... but not the logo I want to be seen!

Can somebody help me? May be there is a good tutorial somewhere about that,...

Hello Marco, Can you share the project file so we can get a better idea of your workflow? Than you.
